or sealed during the winter. This burlap band is in no 
sense a tree protector. Its function is simply to give the 
shelter which the caterpillars seek by day. Unless care- 
fully attended the burlap band does about as much harm as 
good. All burlaps should be applied early in June and 
should be removed at the end of the season. 
Sticky Bands. — Where trees have been cleaned of the 
eggs, but it seems probable that they may become rein- 
fested by caterpillars crawling to them from nearby trees, 
it is well to place a sticky band around the tree below the 
burlap band, thus preventing the ascent of caterpillars. A 
band of cotton with a strip of paper over it, upon which 
is smeared a broad thick band of printers' ink may be used, 
but the ink should not be applied immediately to the bark 
of the tree or injury may result. During the past few sea- 
sons large quantities of "tanglefoot" have been success- 
fully used for this purpose with apparently no injury to 
the trees. 
Fig. 12— An apple tree showing how errors in pruning have resulted in large holes in the 
trunk and branches of the tree. These have been closed up with zinc patches, to pre- 
vent the Gipsy Moth caterpillars hiding and Moths from laying in them. Tree about 
two feet in diameter. (After Stene.)
